Sanwa SW-Gemini-S 2.4Ghz 3Ch FH-E Stick Transmitter with RX-391W Receiver - off-road and track stick radio  [SW-Gemini-S]

Take Control with the Sanwa GEMINI-S Stick Transmitter

The Sanwa GEMINI-S is a compact stick transmitter built for drivers who want direct control and easy tuning. Its feature set supports both fast circuit running and rougher off-road sessions, keeping inputs predictable and repeatable.

Handling Aid and Throttle Shaping

On hard braking the Anti-Lock Braking System (ABS) reduces wheel lock-up to help maintain steering control. Throttle and steering can be refined via Exponential and End Point Adjustment so you can shape how inputs translate to motion.

Flexible Steering and Reversing Options

Servo Reversing and Steering Dual Rate let you swap setups quickly and control steering sensitivity. These options make the GEMINI-S suitable for multi-vehicle use without constant hardware changes.

Trim Accuracy and Power Feedback

Use Servo Sub-Trim for precise centring and micro adjustments that improve straight-line behavior. The Battery Voltage Monitor gives clear feedback on transmitter power so you can manage battery swaps during long sessions.

Model Recall and Receiver Support

Store up to ten models to move between different cars fast. Compatible with RX-391 and RX-391W receivers, the GEMINI-S pairs easily to a range of setups for race day flexibility.

For drivers who value adjustability and a compact stick layout, the Sanwa GEMINI-S presents a solid mix of features for both track and off-road use.
